• The valid range of Temperature input is from -30°C to +60°C.
• When “ATM CORR” in “initial setting 1” has been set to “4. NIL”, “*” is displayed to the left of the temperature value on the correction menu screen. When “*” is on the screen, the temperature cannot be changed. If “ATM CORR” in “initial setting 1” has been set to “3. ppm INPUT”, no temperature is displayed on the correction menu screen.
• Once set, the temperature is displayed at the centre of the top of the measurement screen.
• The factory initial of temperature is “+15°C”.
• Once set, the temperature remains in memory even after the power is turned off.
• Temperature correction is based on 15°C.
If this instrument is used without correcting the temperature, a distance error per 100m is about -0.1mm per +1°C as a temperature difference from 15°C.
A distance error per 100m is about 0.1mm per -1°C as a temperature difference from 15°C.
(For more accurate values, See “12.4 Error when no atmospheric correction is made”.)
